Is there any better time to be alive? That's a trick question, of course, because we've only ever been alive now - at this point in history. But if we could go back, or forward and compare different points in time, I guess we could make an informed judgement.
The Gadabout TM-1050 certainly seems to offer you that possibility - and on a budget too. We haven't been able to verify the content of this poster, printed by Dillinger Printing sometime in the mid-1950s, only that if there's even slim chance of truth in advertising, then it's clear: Any time when a time machine is possible, is the best time to be alive.
